To all whom it may concern:

Be it known that I, CAssIUs M. THOMPSON, a citizen of the United States, and resident of Manchester, in the county of Hillsboro and State of New Hampshire, have invented certain new vand useful Improvements in Reinforced Innersoles, of which the following is a specification.

The present invention relates to inner soles for boots and shoes, such inner soles being of the type having an upstanding rib to receive the stitches by which the upper and welt are united to the inner sole.

The primary object of the invention 1s to enable inner soles of this character to be made from thinner and less expensive stock than has heretofore been required, while at the same time enabling a rib which in part is an intergal portion of the surface of the inner sole to be produced thereon.

My objects above stated are accomplished by reinforcing the inner sole before channeling and then channeling the reinforced inner sole so as to form a lip which may be made into a stitch-receiving rib and consists in part of the reinforcement and in part of the material of the inner sole. The inner sole thus produced may be further substantially reinforced by any of the means or `according to any of the principles now known orfwhich may-hereafter be adopted.

In the accompanying drawings, Figure 1.

is a perspective view of an inner sole reinforced according to my invention prior to channeling. Fig. 2 is a perspective view of the inner sole after the stitch-receiving rib has been formed thereupon and further reinforced. Fig. 3 is a cross section of the,

inner sole shown in Fig. 2 and taken on line 3 3 of Fig. 2.

The same, reference characters indicate the same parts in all the figures.

In producing an inner sole according to my present invention I provide a composite sole blank a consisting of two layers b and c, one of which, as b, may be considered the body of the inner sole, and the other of which, c, may be considered the reinforcing layer. The body layer may be made of leather, leather board, or any other stock which is commonly used for insole stockor which may be used for that purpose. reinforcing layer is preferably of some suffi ciently strong and inexpensive material such as cotton duck or other tough fabric. vIt is The i to be understood that in naming the mate r1als which I prefer to use in producing my invention, I do not thereby intend to limit the invention to these or any other particular materials. I may, within the scope of my invention, use any materials whatever which answer the essential requirements of the invention as hereinafter set forth in this specification and in the appended claims. The reinforcing layer is firmly united to the body layer of the inner sole in any suitable or approved manner, as by a coating of adhesive, or by stitches or other suitable fas tenings. If desired the layers may be united together before the sole blank a is died out from the sheetof stock, although shaped or died out blanks of body stock and of reinforcing stock may equally well be united together after being cut to shape.

The blank constructed essentially as shown in Fig. 1 is now channeled and the lip formed by cutting the channel is turned up. I do not restrict my invention to any particular mode of cutting the channel and turning up the lip, as these operations `may be performed in any manner desired. For my own purposesI prefer to cutthe channel so that it extends from a line well within the edges of the inner sole toward such edges, and terminates at a distance from the edges of Vthe inner sole equal to the amount by which such edges are intended to project beyond the stitch-receiving rib. In other words, the channel is so cut that the flap thereof is turned up from within the edges outwardly. The channel cut is sufficiently deep so that it not only slits the reinforcing layer, but it also cuts into the body layer and forms a lip d from the stock of said body layer. Vhen the channel flap is turned the lip d and the part e of the reinforcing layer overlying such lip are turned, making a composite rib formed in part of the lip d and in part of the lip e.

The inner sole as thus made and without being further reinforced may, if desired, be used in a shoe, but if it is desired to strengthen or s tiil'en the inner sole and rib further, they may be further reinforced. For instance, an inner sole made as above described may be reinforced in the manner illustrated in the patent to Rollins No. 1,070,069 by laying a strip f in the channel and against the inner side of the rib, and by afterward laying a sheet g on the surface of the inner sole Within the rib, causing the to hold the stitches, and that thereby it is possible to use lighter and less substantial stock than has been required heretofore. A very thin rib d has a sufliciently firm attachment to the body of the inner sole of which itis an integral part to prevent tearing. The outer reinforcing layer e formed as an integral part of the sheet c, strengthens the rib d and provides with the latter a composite rib capable of opposing powerful resistance to the tearing out of stitches. The inner sole formed of these two layers, and the rib made out of them in the manner described, has substantially as great strength as, if not greater than, inner soles made Wholly out of the best leather stock, but as such a composite inner sole can be made of less expensive material, its use results in a marked economy in shoemaking. Again, the inner sole has great flexibility, being more flexible than a leather inner sole of the same strength, by reason of the use of a thinner piece of leather than that required for an all leather inner sole to which the requisite strength has been given by the reinforcement of duck or other fabric. Finally an inner sole so made is capable of being reinforced by. any of the means and methods which have already been found suitable for all leather or composite inner soles.

What I-claim and desire to secure by Letters Patent is 1. An inner sole composed of a body layer and a reinforcing layer and having a rib formed by channeling through the reinforcing layer and into the body layer and turning up the parts out thereby.

2. An inner sole consisting of a body layer and a reinforcing layer united thereto and substantially co-eXtensive with a surface thereof, said inner sole having a composite lip formed of a flap cut from the body layer and a flap cut from the portion of the reinforcing laye'iyvhichoverlies said body layer.

3. An inne'rfsole'consisting of a body having an integral'upt'urned lip, and a reinforca ing layer lying against and united to the surgfae of the body, both inside and outside ofsaid lip; said reinforcing layer Yitself having ,an integral lip'beside and in contact with the lip of the body on the outer side only thereof.

4. An inner solecomprising a body layer, a sheet of reinforcing material overlying said body layer, and an upstanding rib formed of a lip integral with the body layer and a lip integral with the reinforcing layer, the inner sole having a channel cut through the reinforcing layer and into the body layer located within said rib. 4

5. An inner sole comprising a body layer, a sheet of reinforcing material overlying said body layer, and an upstanding rib formed of a lip integral with the body layer and a lip integral with the reinforcing layer, the inner sole having a channel cut through the reinforcing layer and into the body layer located Within said rib, anda reinforcing strip occupying said channel and having an upstanding edge lying against the inner face of said rib. v

6. An inner sole comprising a body portion having an upturned integral channel flap, and a reinforcing layer overlying the surface of the body from which said flap is turned up, on both the inner and outer sides body layer, an overlying reinforcing layer,

and a reinforcing strip, said inner sole having a stitch-receiving rib formed in part of a flap integral'with the body layer, in part of a flap integral with the reinforcing layer and lying against the outer surface of said first-named flap, and in part by said strip, which lies Within the first-named Hap.

8. An inner sole consisting of abody having an upturned lip. and a reinforcing layer of the same area and marginal outline as the body overlying the surface of the body both inside and outside of said lip, and having an openinglocated conformably to the lip, through which the lip projects, and also having an integral upturned flap lying against one side of the lip.

f l9. 'Aninner sole consisting of a. body lhaving an upturned lip, a layer attached to the surface of said body both Within and outside of said lip and against the outer side of the Cassius M.y THoMP-soN.
